Sri is highly eulogised as a goddess for her beauty and devotion to Lord Vishnu. In every incarnation of Vishnu she has been his consort.
Lotus is associated with Lakshmi as her asana and attributes. Lotus is a sacred flower representing water as well as self-creation. On a seat of an inverted lotus sits the goddess of beauty and prosperity, in the parayankasana. Although rarely represented without, Vishnu, she sits alone here emanating charm and spirituality. She is depicted as a beautiful deity, slim of waist, delicate limbs and a face that resembles the glow of the rising sun. She wears an elaborate karanda mukuta, jewellery befitting the wife of the sustainer of the universe. One of her hand is raised in a gesture of fearlessness (abhaya mudra) and the other in a gesture of boon bestowing (varada mudra). Every posture of the hand is full of meaning of every instance of the deity is suggestive of some mood and the object carried in the hand has some purpose.
